Sept. 24, 1935. F. BROWN SLEEPING BAG Filed Aug. 29, 1934 FkderioALu Brawn Patented Sept. 24, 1935 UNITED STATES PATENT OFFICE SLEEPING BAG Application August 29,

7 Claims.

This invention relates to a sleeping bag particularly adapted for outdoor use and for that purpose provided with a canopy having mosquito netting and attachment means therefor associated therewith for forming an insect-proof enclosure at one end of the bag body.

An object of the invention is to provide a unit of the kind described which may be readily disposed in operative relationship and taken apart and rolled up into compact form for transportation.

Another object is to provide such a unit having a novel form of attachment means for the mosquito netting whereby interstices along the lines of attachment between the netting and the parts of the bag and canopy are obviated.

Another object is to provide a unit of the kind described adapted for simple and efficient manufacture.

These and other objects are attained by the means described herein and illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of the unit of this invention set up in operative position.

Fig. 2 is a cross-sectional view as taken on line 2--2 of Fig. l and showing the parts in conventional enlarged form for the sake of clarity, parts being broken away.

The unit of this invention comprises a bag body 5 adapted to receive the body of a person and provided at one end, that is the upper end, with suitable openable portions for entry into the bag, these portions not being shown herein since they are readily understood and may be of any suitable form.

At the upper end of the body 5 an elongated fabric sheet member forming a canopy 5 is provided. The bag body 5 is adapted to be disposed flat in the usual way and the canopy G is adapted to be carried upwardly and across a suitable horizontal supporting bar I held by suitable vertical members such as a pair of sapling trunks 8 selected for this purpose. In this position the canopy member provides a rear section 9 and a cover section Ill disposed above the body 5, the front corners of the cover section It) being engaged by suitable guy ropes 22 which retain the canopy in position.

The edges of the canopy, that is, of both the rear and cover sections 9 and Ill, have secured along the edge portions thereof the flexible stripping II. This stripping is preferably attached along one longitudinal edge to the upper surface of the canopy as at I20 so as to be disposed 1934, Serial No. 741,903

in overlying relationship with the surface of the canopy.

Similar stripping I2 is similarly attached transversely of the outer cover I30 of the bag body 5 and along a contiguous lateral portion of said body. This lateral body strip, as seen in the lower right-hand corner of Fig. 2, may be attached to the undersurface of the bag at the edge thereof and continues along the body to the upper end thereof where it connects with the similar stripping ll provided along the adjacent edge of the rear section 9 of the canopy. It will be seen in Fig. 1 that the transverse body stripping l2 and the canopy stripping ll terminate at the top edge of one side of said body, as indicated at l3 and M respectively.

On the inner face of all the stripping above described and on the underlying supporting surfaces to which the stripping is attached, suitable closure means, such as the snap fasteners I5, may be secured.

For forming the insect-proof enclosure, there is provided mosquito netting l6 cut to such dimensions as to stretch across the spaces between the operatively positioned canopy and the bag body. The edges of the mosquito netting are provided with suitable binding l1 and to this binding are secured snap fastening means I8 which cooperate with the similar members provided on the stripping II and I2 and the associated supporting surfaces. It will be seen in Fig. 2 that the snap fastening members are preferably disposed in staggered relationship, since thereby a more effective closure of possible interstices between the binding l1 and the members to which it is secured, is attained.

On the side of the bag body 5 opposite said contiguous lateral portion to which the netting I5 is removably secured, the netting is formed to provide an entry flap I9 which extends below the adjacent side section of the netting and which flap l9, after a person has entered the bag with his head and upper portions disposed within the closure formed as herein described, may be tucked beneath the bag as seen at 20 in Fig. 2, for completely closing up the insect-proof enclosure. The flap l9, at the upper end thereof, may be provided with an extension 2| which embraces the upper corner portion of the bag. It will be seen, that due to the termination of the stripping at l3 and I4, the flap may be readily lifted for entry of the person into the bag.

It will be readily understood that the attachment portions and all the associated parts of the 56 unit have been illustrated in exaggerated form in Fig. 2, for the sake of clarity and that, in reality, these various parts lie fiat and in closely fitting relationship with one another.

It will be apparent that the unit thus provided is an effective protection against insects since all possible apertures and interstices have been obviated by the novel cooperating attachment means of this invention. Other suitable fastening means, such as buttons or so-called zipper fasteners may be utilized in place of the snap fasteners herein disclosed. It is further obvious that the particular shape and disposition of the bag and its canopy may be varied and that the insect-proof enclosure means of this invention could be equally well utilized therewith. Such and similar modifications, however, are believed to be comprised within the spirit and scope of the present invention.

What is claimed is:

1. In a sleeping bag, the combination of a bag body, a canopy attached at one end of the body and comprising a rear section. adapted to be supported substantially upright and a cover section adapted to be supported substantially horizontally above the body, flexible stripping attached to the canopy at the edges thereof, similar stripping attached transversely of the upper surface and along a contiguous lateral portion of said body, mosquito netting, cooperating closure means on all said stripping and on edge portions of the netting whereby the latter may be associated with the canopy and body for forming therewith an enclosure for the associated end of the body, and an extension of the netting forming an entry flap to said enclosure at the side of said body opposite said contiguous lateral portion thereof, said flap being adapted to be tucked beneath the bag body for completely closing said enclosure.

2. In a sleeping bag, the combination of a bag body, a canopy attached at one end of the body and comprising a rear section adapted to be supported substantially upright and a cover section adapted to be supported above the body, flexible stripping attached along a longitudinal edge thereof to the edge portions of the canopy, similar stripping similarly attached transversely of the upper surface of and along a contiguous lateral portion of said body, mosquito netting, closure means on the under surface of said stripping and on the underlying supporting surfaces, and cooperating closure means at the edges of the netting whereby the later may be associated with the canopy and body for forming therewith an insect-excluding enclosure for the associated end of the body.

3. In a sleeping bag, the combination of a bag body, a canopy attached at one end of the body and comprising a rear section adapted to be supported substantially upright and a cover section adapted to be supported above the body, flexible stripping attached along a longitudinal edge thereof to the edge portions of the canopy, similarstripping similarly attached transversely of the upper surface of and along a contiguous lateral portion of said body, mosquito netting, closure means on the under surface of said stripping and on the underlying supporting surfaces, cooperating closure means at the edges of the netting whereby the latter may be associated with the canopy and body for forming therewith an insect-excluding enclosure for the associated 5 end of the body, and an extension of the netting forming an entry flap to said enclosure at the side of said body opposite said contiguous lateral portion thereof, said flap being adapted to be tucked beneath the bag body for completely clos- 10 ing said enclosure.
